I posted this back in March:
There was a teacher in my high school who I was fortunate enough not to ever have who was a complete incompetent boob. He sometimes came to school drunk, failed to show up for work at all on many more occasions, rarely prepared lessons, verbally abused students and basically the kids didn't learn much of anything on his watch. He was encouraged to consider retiring by the Administration, but he blew them off. As a tenured teacher with 25 years of experience, he was rather well paid with good benefits, and didn't want to give that up. Now I support teacher tenure and understand why it is necessary, but this was just flagrant abuse of the system.
My junior year the school started the process to dismiss him, and it got bogged down in a thick muck of red tape, appeals, periods of discovery, hearings, meetings and general paper pushing. It was a full three years before he was actually fired (I kept on following the case through friends of mine after I left for college). He spent another year filing subsequent appeals and lawsuits that went nowhere. The union made excuses for him at every step of the process. Amazing how intensely he fought to keep his job. Had he invested that kind of intensity on actually teaching, then things would have been different.
One of my old teachers that I still keep in touch with told me that this old fart died about three years ago still convinced that he was "railroaded".http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=389&topic_id=5256311
